ROPE-CLAMP.

, SPECIFICATION forming part of Letters Patent No. 762,075, dated June 7, 1904.

Application filed March 17, 1903.

To all whom it may oonccrn:

Be it known that I, ALBERT M. MARsrna citizen of the United States of America, residing companying drawings.

This invention relates to certain new'and useful improvements in rope-clamps, and relates more particularly to a clamp adapted for use as clothes-line holders.

The primary object of the invention is to simplify and improve the construction of a device of this character and to provide a construction in which the ropeor line may be readily placed and as readily removed and in which it is positively held when in position and prevented from slipping.

A still further object of the invention is to construct a device in which the line, rope, or cable may be inserted into the position for being held from the side of the device, thus materially assisting in the ready clamping and also in the secure holding of the line or rope;

Briefly described, the invention comprises a securing-plate provided with a lug or bracket, to which the clamp-lever is pivotally attached, this clamp-lever having a bifurcated upper end and provided with, a grooved inner face which receives the line or rope, the said lever being notched or bifurcated at its lower end, through which notched end the line or rope passes. and between which and the notched side or lug carried by the plate the rope or line is clamped 'or gripped, this grip tightening as the strain or pull on the line or rope is increased. The clamp or holder may be made with a single clamp or lever, or it may be constructed with a pair of clamp-levers, one pivoted on each side of the lug or car.

In the accompanying drawings, Figure 1 is a front elevation of my improved rope-clamp or line-holder, showing the single clamp-lever. Fig. 2 is a side view thereof, showing the clamp-lever in the clamped position. Fig. 3

Serial No. 148,190. (No modeLl is a reverse side view showing the rope or Fig. 4 is a front elevation of the double clamp, the ropes being removed. the same, showing the rope in the clamped position. Fig. dis a front elevation of the same.

To put the invention into practice, I pro- .vide a base-plate 1, provided at suitable points, preferably adjacent each end, with apertures to receive fastening screws ,2, as shown. The plate 1, where a single clam pinglever is employed, is preferably made with one one edge straight and one edge curved, as shown, whereby the one edge of the clampinglever will be substantially in line with the edge of the plate 1, as seen in Fig. 1, which construction enables me to bring the integral clamp-lug, which is carried by the plate, in line with the fastening-screws. The baseplate 1 carries on its outer face, preferably formed integral therewith, a lug or bracket ear 3, which where the form of clamp shown in Figs. 1, 2, and 3 is employed will be set off from the central. longitudinal line of the plate, with said line drawn through the plate from end to end in line with the openings for the fastening-screws. Pivotally attached to this lug or bracket ear 3 is the clamping-lever 4, which has a lug or ear portion 5, that is pivoted to the lug or bracket ear 3 by the rivet or pin 6, this lug or car 5 of the clampinglever being set off toone side of the longitudinal central line of the clamping-lever. The clamping-lever is grooved in its rear face throughout its length in order to form a seat for the cord, line, or cable 7, which is to be clamped, and said clamping-lever at its upper end is bifurcated or notched out to form the recess 8, in order to holdthe line or cable, as shown. At its lower end the clamping-lever is curved inwardly, and this inwardly-curved end 9 is provided with a notch or seat 10 to receive the line or cable 7. The base-plate 1, justabove the lower fastening-screw 2, is provided with a notched lug 11, which is in line with the clamping-lever, the upper face of which lug is inclined and said lug being po- Fig. 5 is a side elevation of sitioned just below the lower end of the clamping-lever, whereby when the upper end of the lever is drawn outwardly the cord or line will be pressed by the clamping-lever at the lower end of the latter and the line or cable firmly held between the said lower end of the lever and thelug 11, the grip of the lever with the line or cable being increased as the weight on the line or cable is increased. The line or cable may, it will be observed, be readily inserted into position back of the clamping-lever from the side thereof, which may be easily accom plished.

In Figs. L, 5, and 6 I show the same principle of clamp with two clamping-levers, the only alteration being that the lug or bracket ear 3 in this construction is mounted centrally of the base-plate l. The clamping-levers are of the same construction as aforedescribed and are pivoted to the bracket-ear, one on each side thereof, and the line is inserted in the same manner from the side into position back of the clamping-levers in order to be engaged and bound thereby against the lugs 11.

While I have herein shown and described the specific construction of the device as it has been practiced by me, yet it will be observed that various changes may be made in the details of construction without departing from the general spirit of my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A rope-clamp comprising a base with a bracket-ear and a projecting lug out of alinement with said bracket-ear in combination with a clamping-lever permanently pivoted to said bracket-ear on one side thereof solely and in alinement with said lug whereby a rope may be introduced between the lever and lug and laid along the clamping-lever from the side.

2. In a rope-clamp, the combination, with a base having a single bracket-ear and two lugs out of alinementwith said bracket-ear of two clamping-levers independently pivoted on said bracket-lever on each side thereof each in alinement with one of said lugs whereby a rope may be introduced between each lug and clamping-lever from the side substantially as described.

In testimony whereof I aflix my signature in the presence of two witnesses.

- ALBERT M. MARSH.
